isolatedstorage

问题 I am using IsolatedStorageSettings to store a contact list for a key in my app. But the app only stores the list till the app is active(i.e. like navigating from one page to another). If I exit the app and again relaunch it, the stored key/contact list is not found. How do i permanently save a list for an app, till the app is installed? Here is the code of my viewmodel, I am using: public class ContactsViewModel : ViewModelBase { private static IsolatedStorageSettings appSettings =

问题 My App wouldn't delete the save files on the loading page in the isolated storage. The codes for the delete and the ViewDiskModel.cs class are below: LoadingPage.cs private void button2_Click(object sender, RoutedEventArgs e) { ViewDiskModel model = lstBox1.DataContext as ViewDiskModel; int m_iSelectedLoad = lstBox1.SelectedIndex; if (m_iSelectedLoad >= 0) { model.DeleteSelectedFiles.Execute(null); } MessageBox.Show("Files Successfully Deleted"); } ViewDiskModel.cs: public class FileItem :

问题 I have accidentally killed one of my WP projects in VS2013. I receovered the source code from the backup, but now, if I try to recompile it and deploy to my device for further debugging, all my app data in the app IsolatedStodage area will be wiped (see this post). The problem is that I have gathered some important data in my app, and need to save them for later use with newer versions of my app. Is there a way to access the file system on a WP device unlocked for development and save the

问题 I am having this error: "Operation not permitted on IsolatedStorageFileStream." I am using visual studio 2010 express for phone c#. Here is my code: public void LoadData() { string xmlUrl = "http://datastore.unm.edu/events/events.xml"; using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication()) { using (var isoFileStream = new IsolatedStorageFileStream(xmlUrl, FileMode.Open, FileAccess.ReadWrite, FileShare.Read, storage)) { using (XmlReader xreader = XmlReader

问题 For one reason or another, I'm using IsolatedStorage with ASP.Net under IIS 8.0(Integrated mode w/ .Net 4.5). This actually works exactly as I'd expect. However, it's very handy to debug isolated storage by looking at the files it creates on your filesystem. I can't find these files. My setup is so that I have a AppPool named TestPool . It has an identity of Jordan (my local user account). The applications seems to work perfectly with data persisting and such. I just can't find where it's

问题 I have a application that needs to download and save files on a device - videos. Videos are short ~ 10min and in poor quality, which means that their size is minimal. So, the problem is that when i download some files - all goes nice, but some files fail with error: Out of memory exception. Logically i think that files less than some size ( for example 50MB ) download nicely, but higher - exception. Here is my code: private void btnDownload2_Click(object sender, RoutedEventArgs e) { WebClient

问题 I'm writing an app for the Windows Phone 7 and although I think I understand how to databind fields, I am unable to databind an image to an XAML element. This is how my image element is defined in my XAML: <image Source="{Binding ImageLocation}" > </image> ImageLocation is a string property. For some reason, my image shows up if "ImageLocation" is a string that points to an image on the Internet (e.g., "http://whatever/image.jpg") but it does not show anything if the image is stored locally

问题 I have an application that stores some data in isolated storage. The data is stored with the Machine-Assembly scope so that all users on the given machine could access this data. Everything seemed to work just fine under admin account, but as soon as we've tested our app under guest account we've run into user permission restrictions. It seems that isolated storage, being just a simple folder generated by the OS, can have some restrictions on user access to these folder. In my case guest
